I just noticed that my Xorg has been producing a core dump every boot, since about 2-2.5 hours after my initial install, 1 week ago.
Investigating led me to try the lts kernel. And boom, core dump.
linux 5.10.15.arch1-1
I’m not even sure what to post to help figure out why it’s dumping. After the dump, X starts up just fine. I’ve had no usability problems, other than I noticed the dump in journalctl on every boot, and the core dump file.
I’m on a Macbbook Pro 11,x.
What would I do to start investigating the reason? Or should I just forget it and live with it?

Looking through boot logs, no dump was produced on this day at 16:10 when I booted. Then, next boot at 16:33, core dump.
Same kernel. (5.10.14-arch1-1) at that time.
Would it be something else installed in that 23 minute window?

Wouldn’t it be you yourself, who installed something in that timeframe (if you are the only one, who uses the said computer)
Nevertheless, you could check that. Just have a look at /var/log/pacman.log

Well, I had just installed the OS that day, and I installed a dozen or more applications within a 2 hour window. My memory is ok, but remembering which packages were installed in that 23 minute window a week ago is a bit tough.
But here’s the pacman log for that window of time. I uninstalled acpilight just now and rebooted, still dumped.

ah ok, i see…
well, i don’ really have a clue. But it could be of interest which DE you are using. My first thougth would be maybe a graphics driver problem. What GPU do you have/use?
What’s the output of inxi -G (maybe you need to install the package first)
Does it happen at random? Or can it be kind of linked with a certain “action” like starting a specific program?

You could check if it is a corrupted file.
journalctl --verify
Also

xorg resp. lightdm is up and running anyways. So if you are sitting in front of the PC you do not even notice that there was an xorg coredump. I only found it because I checked the journal.
This happens with linux-lts 5.10.21-1 and linux 5.11.2.arch1-1.
I do not have a dedicated GPU but use the embedded graphics unit of an AMD Ryzen 5 3400G

Now I have disabled iommu via grub:GRUB_CMDLINE_LINUX="iommu=off"
That seems to fix it. I have to watch it further.
Did you check sudo dmesg for any other info related to errors?
Edit: Do you have the latest UEFI Bios update for your board? Mine is an MSI and the latest update is perfect. I have no issues and i run with iommu=on controlled by the board in the settings.

The PC has an MSI B450-A PRO MAX with latest M.C0 BIOS.
And I just realized that the xorg coredumps also happen with iommu=off

AMD Ryzen 5 3400G
Have you looked at this?

Edit: I have core dumps too if i list them. coredumpctl list

Well, my problem is not the core dump itself. My problem is that xorg crashes and I want to know why.
Check your Ram timings and voltage settings. Are you using XMP?
Example: Instead of 15-15-15-15-36 it may need to be 16-18-18-18-36 and make sure Frequency is correct if it is 3200MHz and voltage 1.350V as an example.

The RAM is ok. memtest86 does not find any issue. It is XMP RAM but instead of the 3200 MHz it is made for I run it at 2933 MHz because that is max for the board.
mbod:
MSI B450-A PRO MAX
The system spec on the processor is 2933 but the board does up to 4133 OC so you should be able to set your ram at 3200 if that is what you have.

You are right 2933 is max for the CPU and not for the board.

The log tells that lightdm.service fails because of Xorg crash. lightdm saves a copy of the xorg log to /var/log/lightdm. This is what it says:

This seems to be the culprit:
Xorg: ../xserver/dix/privates.c:384: dixRegisterPrivateKey: Assertion !global_keys[type].created failed.
After that crash lightdm is restarted several times until it succeeds:
lightdm.service: Scheduled restart job, restart counter is at 3.
For me (made a post about this very issue in January) was a combination of NVIDIA drivers and the 5.10 kernel.
And since you run the 5. 10 kernel instead of the latest And t h e LTS kernel also now is 5.10…
Do you run Nvidia drivers? In that case either upgrade to 5.11 or remove the proprietary Nvidia drivers.

I have found an interesting fact:
When X crashes the log files show that X loaded the following modules:
[ 5.858] (II) LoadModule: "glx"
[ 5.859] (II) LoadModule: "ati"
[ 5.859] (II) LoadModule: "radeon"
[ 5.859] (II) LoadModule: "modesetting"
[ 5.859] (II) LoadModule: "fbdev"
[ 5.859] (II) LoadModule: "vesa"
[ 5.891] (II) LoadModule: "fbdevhw"
[ 5.891] (II) LoadModule: "fb"
[ 5.892] (II) LoadModule: "shadow"
[ 6.251] (II) LoadModule: "libinput"
[ 7.023] (II) LoadModule: "modesetting"
[ 7.040] (II) LoadModule: "glamoregl"
[ 7.125] (II) LoadModule: "fb"
When X is not crashing I see the following modules in the og:
[ 7.919] (II) LoadModule: "glx"
[ 7.921] (II) LoadModule: "amdgpu"
[ 7.926] (II) LoadModule: "ati"
[ 7.931] (II) LoadModule: "modesetting"
[ 7.932] (II) LoadModule: "fbdev"
[ 7.932] (II) LoadModule: "vesa"
[ 7.942] (II) LoadModule: "fbdevhw"
[ 7.943] (II) LoadModule: "fb"
[ 7.943] (II) LoadModule: "dri2"
[ 7.986] (II) LoadModule: "glamoregl"
[ 7.998] (II) LoadModule: "ramdac"
[ 8.122] (II) LoadModule: "libinput"
The main difference I see is radeon vs. amdgpu. It looks like the first X start is with radeon, that fails and then amdgpu is used.
I blacklisted the radeon module now. Lets see …
I wonder if you create this file
/etc/X11/xorg.conf.d/20-amdgpu.conf
Section "Device"
Identifier "AMD"
Driver "amdgpu"
EndSection
